' l 3 Claims. 1

This invention relates to industrial brooms of the type adapted to bepushed or pulled, and in particular a tubular handle having a swiveljoint whereby the broom may be set at different angles in relation tothe handle.

The purpose of this invention is to provide means for adjusting theposition of a broom in relation to a handle orfacilitating cleaning inclose quarters such as narrow aisles, and in corners and the like.

Various methods have been provided for connecting broom handles tobrushes and brushes have been positioned at different angles in relationto a handle. However, to facilitate cleaning in close quarters thisinvention contemplates a tubular broom handle having a swivel head witha latch for holding the head in different positions in relation to thehandle.

The object of this invention is to provide an improved swivel mountingfor industrial broom handles whereby the position of a broom carried bythe handle is adjustable from the upper end of the handle.

Another object of the invention is to provide a handle for industrialbrooms and the like in which the handle is adapted to be used withconventional brooms now on the market.

A further object of the invention is to provide a tubular handle forindustrial brooms which is of a simple and economical construction.

With these and other objects and advantages in view the inventionembodies an elongated tubular handle having a fitting providing abearing for a spindle on one end with a latch device extended throughthe handle for retaining the spindle in an adjusted position, with afrustoconical shaped section on the end of the spindle for retaining thehandle in openings in the back of a broom.

Other features and advantages of the invention will appear from thefollowing description taken in connection with the drawings wherein:

Figure 1 is a side elevational view illustrating the improved tubularhandle and showing the handle in an opening in the back of a broom, theback of the broom being broken away and shown partly in section.

Figure 2 is a plan view of the industrial broom handle showing a scraperblade mounted on the fitting or head and showing an open hook or ring atthe opposite end of the handle, part of the handle being broken away.

Figure 3 is a longitudinal section through the handle taken on line 3 3of Figure 2, also with parts broken away.

Figure 4 is a sectional plan taken on line Il-I of Figure 3 showing theconnection between the handle and the i'ltting or head.

Figure 5 is a vertical section through a tting or head, similar to theone shown in Figure 3 but having a threaded spindle, with parts brokenaway showing the spindle in elevation and showing a scraperblade on theupper end with the blade turned through an angle of degrees.

Referring now to the drawing wherein like reference characters denotecorresponding parts the improved industrial broom handle of thisinvention includes a tubular handle I0, a fitting Il providing a head, aspindle I2 journaled in the fitting I I, a latch bar I3 and a scraperId.

The tube Iii is formed as illustrated in Figures 1 and 3, having athreaded lower end I5, which is threaded into a side connection I5 or"the ttings II, a threaded upper end I'l on which a cap IS is threaded,and a slot I9 which, with the parts as shown in Figure 3, is positionedin the under surface and extends through the end of the tube.

The fitting Il is formed with a T and the T is bored on the longitudinalaxis providing a bearing for the spindle I2. The spindle I2 is providedwith a plurality of radially disposed openings 20, the openings beingpositioned to receive the end of the latch bar I3 that extends throughthe tube I0 and that is provided with bearing washers 2 I, which centerthe bar in the tubel and a pin 22 which forms a trigger, and whichextends through the slot I9. The upper end of the tube It is providedwith a spring 23, one end of which is located on the end of the bar I3and the opposite end of which is positioned over a ball 24 on the innersurface of the cap I8.

The outer surface of the cap I8 is provided with an angularly disposedopen ring or hook 25 which provides a handle.

With the parts arranged in this manner the latch bar I3 is withdrawn bythe trigger 22 whereby the spindle I2 may be rotated to adjust theangular position of the broom in relation to the handle and with thebroom in the desired position the trigger 22 is released whereby thespring 23 snaps the bar I3 into one of the openings 2@ of the spindle.

The upper end of the spindle is provided with a plate 26 having a flange2l on one edge and a scraper blade hiis held against the mounting platewith a cap screw 28 that is threaded into an opening 29 in the upper endof the spindle. With the parts in position the mounting plate 26 may besecured to the end of the spindle by welding, as indicated at the point36 or by other suitable means. The scraper is provided with a beveledscraping edge 3l and the sharp edge of the scraper may be extendedupwardly as shown in Figure 1 or the scraper may be turned aroundwhereby the sharp edge extends over the handle as shown in Figure 5.

In the design illustrated in Figures 1 and 3, the lower end of thespindle I2 is provided with a frusto-conical shaped section 32 thatholds by friction in afcorrespondingly shaped iopening A33 of a broomheadl 34 from which bristles35 extend, whereby the broom head or back isfrictionally mounted on the handle.

In the design shown in Fgvure 5,-the frustoeY conical shaped section ofthe spindle which in Figure 5 is indicated by the numeral 38,"is'proings therein extending at an acute angle to a horizontal planepassing through the broom head comprising an elongated tube, a headcarried by one end of the tube, a spindle having radially disposedopenings therein journaled in the tube head and having an end extendedfrom one end of the tube head to be inserted into one of the openings inthe broom head for attaching the broom head directly to the spindle atan acute angle to the horizontal' plane passing through the broom head,and a trigger actuated latch bar extended through the tube andpositioned to extend into one of said openings of the spindle forholding the broom .head'onsaid spindle in adjusted posivided withthreads 31 withwh-icnthe `spindle may be threaded into an opening in aback of a broom. The spindle 36 is provided with a` frustov conicalshaped section 38 at the base of the threads.,l` :In this design-tubelflatchlbar I3, fitting: llgand scraper-Idware the. same -as illustratedin Figures 1 and 3. l. f

Withthehandle, as illustrated in IFigures 1 and 3 orasuinFigure 5 thebroom and scraper are adjustablylmounted on the lower end ofa broomhandle ,and the broomgmay readily be adjusted to diilerentanglesginfrelation to-the handle and the scraper turnedtoaan extended orretracted position, asmay be desired..

It will b e yunderstood that other modications maybe madein the designand arrangement of the partswithoutdepartingfrom the spirit of theinvention:

1. The combi-nationpf Va broom handle for a broom head vhavingfrusto-conical shaped opentionsin relation to the tube.

2. In the combination as described in claim 1 in which amounting plateis provided on one end of the spindle and a cap screw is threaded intothe end of the spindleon which the mounting plate is positioned forclamping objects to the end of the spindle 5 3. In the combination asdescribed in claim 1, Wherein-ithe handle is provided .with resilientmeans :for urging.; the latch bar towardv the spindle.
